The author thinks that mentally poking the bodymap created by the brain can cause changes in the actual processing. I wouldn't believe this without proofs other than introspection(1). Technically, the vagus nerve can carry enough information to produce speech (the gut should be articulate, of course), but it certainly nowhere near the corpus callosum or the spinal cord. I doubt that it can allow to "coordinate the rest of our body". (1) As far as know conscious manipulation of the heart rate is achieved by changing respiratory patterns, not thru direct control of the signals that the brain sends there.
